Table 6: Default values of the DMS access methods

The value 0 with getRecordLength() designates the value “variable - only limited by block size” for the SAM and ISAM access methods and the “pubset-specific default” for UPAM.

The values 0 with getBlockSize(), 0 with getPrimarySpaceAllocation() and -1 with getSecondarySpaceAllocation() designate the “pubset-specific default”. If the file has been created, the current values are entered here.
